How locate a JPanel in a JPanel (SOS !!!)

I add the class affectation (see below) in a JPanel but I can't succeed in locating it in this JPanel..
I have tried to use setLayout(null) and to use setLocate and setBounds but it doesn't work..
Thanks
public class Affectation extends JPanel{
public Affectation(int deb, int fin,Color couleur){
this.setBackground(couleur);
this.setBorder(BorderFactory.createLineBorder(Color.black));
//this.setBounds(new Rectangle(deb,10,fin-deb,20));
this.setLocation(deb, 7);
this.setPreferredSize (new Dimension(fin-deb,20));
this.setMinimumSize (new Dimension(fin-deb,20));
this.setMaximumSize (new Dimension(fin-deb,20));
}

You have to locate Affectation in the container you add it to.
JPanel otherPanel = new JPanel(new NullLayout());
Affectation myAffectation = new Affection( deb, fin, coleur);
otherPanel.add(myAffectation);
myAffectation.setLocation(deb, 7);
other something like that.
Cheers

How to add JPanel in JComboBox?

Hi.
How to add JPanel in JComboBox...?
Regards
Bilal

I do not know much about Cardlayout.
As far as I know, it is a layout which let you assign a serveral 'card' and exist together. By consider the order of the card, you could change the view of each page by using method- first, last, next etc. However, I would like to know what if I got a number of buttons, say A B C D E F, and having cards called a b c d e f,I know I could change from a to b, but what if I want to change from c to e by pressing the button E (assuming it showing the c card now).
Actually, I was able to create the code now which adding one JPanel to another now. First create a JPanel with prefer size, min max size.
then add a JPanel into the CENTER of the above JPanel, both using borderlayout.
But having a little difficulties, could I add more JPanel into the CENTER such that one overlapping each other, by those Buttons, through action and event, hide those which I do not want to show?
Like A B C buttons, a b c panels. When press A hide b c and show a, so on.
Could I use method like movetofront(something like that, forgot detail which read in a book) to do this?
Cheers

}When i execute this i get this:

How to resize JPanel at Runtime ??

Hi,
Our Project me t a problem as below, we hope to resize JPanel at Runtime , not at design time, ie, when we first click the button called "Move JPanel" , then we click the JPanel, then we can drag it around within main panel, but we hope to resize the size of this JPanel when we point to the border of this JPanel then drag its border to zoom in or zoom out this JPanel.
Please advice how to do that??
Thanks in advance.

When adding components to a null layout you must set both a location and size for them to show up.

Locate a JPanel in an other JPanel (HELP !!!)

I add the class affectation (see below) in a JPanel but I can't succeed in locating it in this JPanel..
I have tried to use setLocate and setBounds but it doesn't work

public Affectation(int deb, int fin,Color couleur){
this.setBackground(couleur);
this.setBorder(BorderFactory.createLineBorder(Color.black));
//this.setBounds(new Rectangle(deb,10,fin-deb,20));
this.setLocation(deb, 7);
this.setPreferredSize (new Dimension(fin-deb,20));
          this.setMinimumSize (new Dimension(fin-deb,20));

How to find JPanel viewable or drawing area size

hi,
I have a two small question. First one is, I have a JPanel what I need is to find the viewable area size or the drawing size of the Panel. I don't want to get the size of the Title bar. All I need is how to find the actual drawing area not including the title bar. I know how to get the total size of the JPanel, I just needs to know how to get the drawing area size where you put your components. e.g. if the size of my Panel is (300,300) then it also includes the title bar and the border too. But I need to find or get only the area size where we actually put our components.
Another question is how can I get the size of my Title bar means the width and height.
I'll really appreciate for any help
Thanks

How to make JPanel as JTable Cell Editor (Urgent help needed)

Hi!
I want to make JPanel (with a JTextField, 3 JLabels and 1 JTextArea) as cell editor for one column. Can somebody help me on this?
Does anybody have any sample code? I will greatly appreciate ur help.
Thanks,
Snehal

Okie. In "How to use JTables" page found in the JAVA website (there is a link from the JTable section of the JAVA API documentation), there is a sample code for a sample color chooser. What this does is, adds a button with its action listener set to pop up a color chooser window. In this, rendering is still through a JLabel.
This example would be of good help to you. Plus, this example gives me a feeling that what u ask is possible.

How can make Jpanel response click event?(help!)

in a program i want to make jpanel response mouseclicked event, but jpanel class does not provide addActionListener(). through which way? i am able to arrive at the purpose! (create a new class extends jpanel, how to do?)
thank a lot!!!

Hello,
have a look:import java.awt.Color;

[GUI programming] How do two JPanels interact?

Hi, all
I've been looking if there is a standard/mostly-used way implementing GUI applications. e.g.,
under a JFrame, there are 2 MyPanel exntending JPanel, one placed on the leftside, the other on the rightside. they both have got a bunch of JButtons, JLabels, JList, etc. this is the view.
but for the control part, here comes the question: I'd would like PanelA to change background color if a Button on PanelB is pressed. where should I place this part of code that controls what happen. I've considered some possibilites, but not sure which one is the best.
1. implement it in main() like: if PanelA.Button.isPressed(), then PanelB.setBackground(Green)
pros: centrailized control
cons: could lead to long & messy code if there are many Panels needed to control
2. PanelA as Observer, PanelB Observable
pros: doable
cons: not very convenient
3. PanelA & PanelB both singleton, so they can reference to each other directly
pros: easy implementing
cons: less flexibility
if none of them is the way you do, how do you do it then?
any help will be appreciated.
thanks.

You missed the obvious one, just let the controlling panel have a reference to the color panel. In your frame:
ColoredPanel coloredPanel = new ColoredPanel();
ControlPanel control = new ControlPanel(coloredPanel);
// add to conten pane, etcThough ultimately your option two is the best one.

How to save JPanel in HashMap and then build tree using this HashMap

Actually I'm not sure I'm on right way... what I need to do is to build a tree of tests.
I can imagine that this can be done in such way
1. add all jpanels into hash map HashMap<String, JPanel> or HashMap<Vector, JPanel> ?
2. build tree from this hash map
3. each node contains jpanel
+root
|
+suite1
|
test1 -------------> jpanel with components
|
test2
|
+suite2
|
test21
|
test22
If somebody has an idea how to cope with this, please help!

Yes, I've tried, but i didn't find appropriate option. In Easy setup I can only choose presets. I've tried to edit capture presets, but there were no Log and Capture window settings.

opaque(boolean), but i fail to do it, here is my code,
i really need ur help.......thankx a lot
Well, the transparent part is easy. You should be calling setOpaque(false) rather than setOpaque(true). This will eliminate background painting of the JPanels.
The overlapping can be accomplished in multiple ways, but NOT using BorderLayout. You'll either want to do as one person suggested and use no layout manager and position things absolutely, or as another suggested and use JLayeredPane.
Personally, I would suggest a third approach that uses a single JPanel to do all of the painting. Something like this would work nicely:
public class DrawPanel extends JPanel {
    public DrawPanel() {
        setOpaque(false);
    public void paintComponent(Graphics g) {
        super.paintComponent(g);
        drawBase();
        drawGraph();
    public void drawBase() {
        g.setColor(new Color(0,255,0));
        g.drawOval(50,50,50,50);
    public void drawGraph() {
        g.setColor(new Color(255,0,0));
        g.drawOval(20,10,10,10);

How to refresh JPanel?

Hello
I'm writing applet and I got stuck. I have JPanel which is in createAndShowGUI() and it's invoked from init() with invokeAndWait. This JPanel contains array of images. I'd like to
remove JPanel and paint different configuration of images. All in the same applet window. This would happen after I pushed one of the images.
How can it be done?.
Cheers

you can use keyword "repaint". you can write that keyword to the method void paintComponent(Graphics g). or you can use remove method from JPanel and create the new JPanel
